hi
here i need more help in the following questioins::
1) when a base band signal m(t)=2cos2000t+cos3000t is modulated using a carrier cos20000t, the frequency component in the USB of DSBSC are given in rad/sec. ( also mention the logic behind the answer or formula)
A. 17k and 18k
B. 22k and 23k
C. 18k and 22k
D.17k and 23k
2)
for tone modulation (AM/DSB with carrier) the power effeicency is ??
3)bandwith of the DSBSC signal, modulated with baseband signal with the band with 100 hz is ???
4)
for the message signal m(t) =sin(square)1000t the baseband frequencies in rad/sec are????
please ans these question if anyone have the answer.
its an urgent
best regards
